Cufes2 roasting
WebSolution Verified by Toppr Correct option is B) Chalcopyrite ( CuFeS 2) Roasting is the process of heating the concentrated ore i.e. Sulphide ore of metals. Partial roasting of Chalcopyrite follows given reaction: 2CuFeS 2+O 2→Cu 2S+2FeS+SO 2↑ 2Cu 2S+3O 2→2Cu 2O+2SO 2↑ 2FeS+3O 2→2FeO+2SO 2↑ WebCopper is obtained from sulfide ores through a two-step process consisting of roasting the ore in the presence of oxygen and heating the resultant copper (I) oxide with powdered carbon. The overall reaction is as follows: 2Cu2S (s) + 302 (g) + 2C (s) → 2SO2 (g)+ 4Cu (s) + 2CO (g) Calculate the maximum yield of copper obtained from 1.60 kg of Cu2S.
